Milwaukee M12 battery cell chemistry

I had just bought a Milwaukee M12 screwdriver 2401-20. Would any body know what type of lithium batteries are used in them? I was thinking an 18650 battery of lithium manganese possibly? I was wondering what type of cell i could rebuild them with down the road.

I don't know the answer to the question, but I just discovered that BOTH my M12 batteries that are about 2.5 years old are dead (charger reporting damaged cells) I only charged them about 5-6 maybe 7 times each, I'm going to call Milwaukee on Monday and see what they say. The battery warranty is only 2 years but Ill give it a shot.

I have 12 and 18 volt Milwaukee tools I use at work. I have had all kinds of problems with them(batteries) over the years, and The local Milwaukee Rep. has replaced them no questions asked. He also told me that Milwaukee is remodeling these batteries and they will be under the same part number, but they will be called "RED"? Anyway I have some of these and no problems so far. Great tools!!!
